Help! All lights on dash are on

[fpilot]

Hi everyone! I have a 1986 560sl and last night I let a friend who loves to race their car, drive mine and see how peppy my car is. Well they floored it on the highway. I have never treated my baby like that. He said it got to the red line and all the lights on the dash came on (battery, oil, gas, abs brakes, all). The car still drove and drives fine but the lights will not shut off even after I turned the car and let it sit over night. What happened to my baby?

Thank you!
